Solution 3. Reboot the Power Cord

When a hard drive is not detected, it can prevent the boot manager from being accessed, leading to a "missing boot manager" error. This issue may be caused by improperly connected power and data cables, which can prevent the computer from recognizing the hard drive.

Follow the steps to fix it:

Step 1. Carefully open your computer case to access its internal components.

Step 2. The hard drive is typically located in a designated bay within the computer case, and it's connected to the motherboard via a SATA cable. The power cable, on the other hand, is usually connected to the hard drive from the power supply unit (PSU) in the computer case.

Step 3. Restart the system by disconnecting and then reconnecting the power and data cables to resolve potential power or data connection issues.

Step 4. After adjusting the cables, turn on your computer and see if the issue is resolved.

Note: Be cautious when taking these actions as a small mistake can cause physical damage to your PC or laptop.

Solution 4. Change Boot Order in BIOS

Here are the steps to modify the boot sequence on a computer, in one paragraph:

Step 1. During startup, press the F2 or Delete key to access the BIOS menu. This allows you to configure basic settings for your computer.

Step 2. Locate the "Boot" or "Boot Sequence" settings inside the BIOS.

Step 3. You can find a list of bootable devices and their current order in these settings, where you can rearrange the sequence to match your desired method for Windows installation. For example, if you're using a flash drive, set it as the primary boot device.

Step 4. Save the changes and restart your computer.

These steps will resolve the issue and give you access to the Boot Manager as needed.

Other problems related to the boot error:

Solution 5. Create a New Boot Sector

A "missing boot manager" error can be caused by partition corruption or boot damage, often within the Windows partition, due to factors such as an old hard drive, virus infections, or malware attacks. To resolve this issue, you can try creating a new boot sector by following the suggested steps.

Step 1. Start by accessing the start menu and searching for "Command Prompt."

Step 2. To enable developer configurations, right-click the Command Prompt option and select "Run as administrator".

Step 3. Type "bootrec /fixboot" into the Command Prompt and hit Enter to execute it.

Step 4. The command was successfully executed, and a message indicating completion was displayed.

Step 5. Restart your PC by pressing the "Ctrl + Alt + Del" keys and selecting the restart option.

Note: Before restarting your system, please disconnect any removable devices like USB drives or external hard drives.

Solution 6. Rebuild Windows BCD

When your Boot Configuration Data (BCD) becomes corrupted or misconfigured, rebuilding it is necessary to resolve the "Windows boot manager is not showing in BIOS" error. The BCD serves as the gateway to accessing the boot manager, and without it, the manager's options and visibility are hidden.

Follow the steps:

Step 1. To change the Advanced Startup Options, search for "Change Advanced Startup Options" in the taskbar's search field, then click on it to open the settings after it shows in the search results.

Step 2. In the advanced startup option, click on "Restart now". This action will redirect you to the advanced options menu.

Step 3. Choose "Troubleshoot," and then choose "Advanced Options."

Step 4. Choose "Command prompt" from the subsequent menu and wait for the Command Prompt to open.

Step 5. In the Command Prompt, type "bootrec/rebuildbcd" and press the "Enter" button, then wait a few moments until you see a successful installation message, after which you must adjust the attribute files in the next step.

Step 6. In the same Command Prompt, type "attrib c:\boot\bcd -h -r -s" and press Enter to remove the read-only and hidden files from the Windows bcd. Then, enter the command "ren c:\boot\bcd bcd.old," to rename the stored bcd, giving you access to rebuild the BCD file.

Step 7. Run the command "bootrec /rebuildbcd" and press Enter. It will ask you to add a boot to the list, type "Y" and hit Enter. Wait a few moments for the "Operation successful" message to appear on the screen.

Step 8. To resolve the issue, restart your computer or laptop to see if the problem is resolved. This simple step can often resolve problems with your system.

You can try Qiling Disk Master for a quick and easy way to solve this issue, which also simplifies the process of rebuilding MBR.

Solution 7. Replace A Hard Disk

Old and outdated hard drives can cause issues with the Windows boot manager not appearing in BIOS, so it's recommended to replace them with a new one, which can be done by a computer technician due to the technical expertise required.

If you're using a Dell laptop, you can refer to this tutorial for assistance.

Solution 8. Enable the Boot Menu via CMD

The boot menu is crucial for managing BIOS and other essential computer functions. On the other hand, the boot manager is usually hidden on the startup flash screen and is turned off by default. However, it can be easily activated using simple Command Prompt commands.

Follow these steps:

Step 1. To open the Command Prompt, search for "Command Prompt" in the search bar of the taskbar.

Step 2. To open the Command Prompt as an administrator, right-click on the Command Prompt icon or the "Command Prompt" entry in the Start menu, then select "Run as administrator" from the context menu. This will open the Command Prompt with administrative privileges, allowing you to run commands that require elevated access to the system.

Step 3. Type the following commands and hit enter in the Command Prompt.

• bcdedit /set {bootmgr} display bootmenu yes
• bcdedit /set {bootmgr} timeout 30.

Step 4. When the "Operation successful" message appears on the screen, it indicates that the command has been executed successfully.
